Abstract: An objective of the present invention is to provide novel useful elastin production-enhancing agents that have a remarkable ability to enhance elastin production. The present invention provides elastin production-enhancing agents that include at least one component selected from the group consisting of the peptide Leu-Glu-His-Ala (formula I; SEQ ID NO:1), derivatives of the peptide, and salts thereof. The present invention also provides elastin production-enhancing agents that include at least one component selected from the group consisting of peptides which include a conservative substitution, deletion, and/or addition of one or more amino acids in the amino acid sequence of formula I that retain an ability to enhance elastin production in cells; derivatives of such peptides; and salts thereof.

Abstract: An antifatigue composition for reducing muscular fatigue or the like during or after exercise, which includes an imidazole compound obtained from extracts of fishes, shelifishes, fowl, flesh or the like, as an active ingredient. The imidazole compound in the antifatigue composition is preferably at least one compound selected from the group consisting of histidine, anserine, carnosine, valenine and salts thereof. The antifatigue composition preferably further contains D-ribose as an active ingredient. By orally ingesting the antifatigue composition, the amount of lactic acid in plasma during or after exercise can be kept low, and therefore muscle fatigue caused by exercise can be controlled, and as a result, the ability to exercise can be improved.
